Soldiers who once wore combat fatigues — or, as some call them, “pajamas” — to work at the Pentagon will have to dust off their ironing boards, as the Army announced Tuesday a new Pentagon dress code requiring the formal service uniform.

The wardrobe change came after Sgt. Maj. Raymond F. Chandler III took suggestions from soldiers he talked with in the field.

After the terrorist attacks of Sept.11, 2001, then-Defense Secretary Donald Rumsfeld had soldiers at the Pentagon wear combat fatigues, in part to remind them the country is at war.

Now nearly 10 years later, the Army is taking a more business-like approach to its Pentagon presence.

“The business part of the Army is done in the Pentagon,” Chandler told Army News Service. “And as a professional, there are certain standards of attire associated with certain activities.”
